Discover the definition of the term Multi-Factor Authentication (Mfa) presented by Les Assises de la Cybersécurité.


To authenticate a user, the most common option is to ask them for their password (""what they know""). But there are other approaches, such as biometrics (""what they are"") or the use of an object in their possession, such as a mobile phone or an electronic device, both of which are capable of issuing a single-use code (""what they have""). Multi-factor authentication involves supplementing the password with at least one of these factors, in particular to offset the risk of password theft.

Biometrics are limited to fingerprints, the palm of the hand or the retina. Beyond that, beware.
